1. Introduction

Re-thinking of the way we market MDE: not as a way to do things faster, but as a way to do new things.

— Whittle et al., 2014

2. Our claim

Computational science can benefit from Model-Driven Engineering…​ and vice-versa!

3. Model-Driven Engineering

4. What is a model ?

5. What is a model ? (for us)

  • A set of diagrammes, views, rules …​

intro sysml

6. What is a model ? (ctd.)

  • more precisely, a set of artefacts

arbre

7. What is a model ? (ctd.)

  • Scientific models vs. Engineering models

  • Differential equations vs. Class Diagram

  • Tooling scripting vs. MDE

8. Scientific models

Bottom-Up approach

scientific method

⇒

MATLAB

9. Engineering models

Top-Down approach

airbus 300

⇒

MATLAB

10. What is MDE ?

Meant to increase productivity by maximizing compatibility between systems via reuse of models.

11. Scripting vs. MDE

Scientific models:

  • pipe

  • scripting "unix-like"

Engieering models:

  • openData

  • metamodels

  • transformation

31. Lesson learned

  • Gap is getting smaller

  • Both modeling "worlds" are mature

  • Communities are ready for collaborations

32. Challenges

  • Build relevant model transformations

    • static and dynamic analysis

    • import / export with existing tools

  • Domain-specific animation

  • Domain-specific property languages

35. Recap

  • Engineering/Scientific models are converging

  • Our domains would benefit from Cross-fertilizing

  • We can bring expertise in MDE to your domain

  • Other DSL framework than EMF or MPS: e.,g., OpenFlexo

  • We need partners for H2020, ITEA3, …​
